You can't use your old sim from the other contract.You have two best options

• Call customer service and ask them to send you another sim
• Go into your nearest O2 store and ask them for a new sim with your number that you lost. 

Did a new sim come with the phone? If so then ask O2 customer service to provision that sim and activate it. 

I would advise you to call them around 8.30am and they will sort out exactly the best way to sort it for you. I certainly wouldn't use live chat myself but that is one of the ways to contact them.

Firstly @Anonymous Any lost sim has to be reported .

This should be reported immediately.

Have you lost the sim from the iPhone X with 30gb data tariff?.

Contact customer services tomorrow morning (after you have reported the loss) and explain the situation. They will advise the best course of action with regards using another sim to continue with your current tariff...https://www.o2.co.uk/contactus

This can be done on the same call. If you have a sim then give them the sim serial number. By provisioning that it will automatically wipe yourost simultaneously making it unusable. Some help I'd you need it :
